How does the torque converter work on a 700R4?
The 700R4 torque converter’s lock-up (clutch) system creates a physical connection between the impeller and the turbine, transforming the torque converter into a mechanical coupling. This internal clutch locks the converter when engaged by the Torque Converter Clutch (TCC) solenoid (a pressure switch inside the transmission to engage the lock-up).
What kind of transmission does GM 700R4 have?
The 700R4 and 2004R were the first GM automatic transmission to come from the factory with a locking torque converter. This allowed for a true 1:1 connection between the engine and rear wheels at high speed, which increased fuel economy.
What to do when your 700R4 transmission won’t lock?
When your 700r4 Transmission is slipping or won’t lock, it’s most likely a problem with the converter inside the transmission. However, the first thing you always should to when your transmission is slipping is to replace the transmission fluid and to flush the transmission.
What’s the difference between a torque converter and a transmission?
Whereas, a manual transmission clutch provides a direct physical connection between the engine and the transmission. That’s why at a stop the clutch must be disengaged from the flywheel. The torque converter bolts to the input shaft of the transmission and uses the same hydraulic transmission fluid that the transmission uses.

Can a torque converter be a problem with a transmission?
It could be a problem with the transmission, or the transmission could be perfectly fine and it could be a problem with the torque converter. Torque converter issues on a lot of older transmissions can be diagnosed by carrying out a stall-speed test. Below we have outlined how you can safely and easily conduct a torque converter test.
What kind of valve body does TransGo 700R4 have?
This kit was designed for 1982-1987 units with a type-1 valve body; however, it will fit all year models and valve body types. If you have a 1988 or later type-2 valve body, you can use the more economical “junior kit”, our part # SK 700-JR and achieve the same results.
